A fan in the seats held up a sign that read “E-Rod” before the official scorer at Yankee Stadium could retract what appeared to be an eighth-inning error charged to Alex Rodriguez when A-Rod retreated from and then misplayed an Edgar Renteria grounder with two out.

Howie Karpin, the scorer, reasoned that the ball took a funny bounce before A-Rod muffed it, and Rodriguez escaped without being charged with another blunder in a 7-2 loss to the Red Sox.

When it comes to Rodriguez and playing the field this season, it hasn’t exactly gone as well as it did last year when A-Rod, a two-time Gold Glove shortstop, made the smoothest of transitions to a new position.

This season though, Rodriguez’ glove has haunted the Yankees all year with eight boots at the hot corner.

Because of the opponent, these things will always be magnified. Earlier this season, Rodriguez came up with a big error against the Red Sox trying to field a Manny Ramirez grounder April 6 during a five-run Boston rally.

The Sox scored three runs around another A-Rod error with Johnny Damon the batter on April 11.

“You don’t mind making mistakes when you’re aggressive,” Rodriguez said. “I feel pretty good and we’ll keep working on it and we’ll be fine.”
